I played this when I was a kid and more than a few of geography facts stuck with me. It's pretty fun. It's one of the more challenging Carmen Sandiego games (at least to an American).

I docked it one star because there are a few annoyances in the game. One is that you may not get enough clues as to the identity of the culprit before finding them, forcing you to fly back to a prior city and investigate more (and even then you may not get another clue). Sometimes you may just have to get a warrant based on a pure guess, which does not seem like valid police procedure to me. Also, the "Scanning..." robot takes forever.

PS, you will need this copy-protection key if you want to play more than one case:
